I'm getting enough MCM work on WCG to keep my machines busy.
My cache setting is 2.0 days. My machines constantly poll for new work since the supply is limited.
Well, after 8+ years of contribution to WCG, I manage to sneak into the top 100 point contributors per free-DC stat. The gpu OPNG tasks certainly help to achieve this goal quickly. With cpu tasks, it will take a long long time, lol.
